DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The specific structure of the sealing material squeezing device of the present invention will be described below with reference to the illustrated embodiment. FIG. 1 is an exploded perspective view showing an example of the sealing material squeezing device of the present invention. As shown in the figure, 2
The two leg members 1 and 1 having a substantially C-shaped cross section are arranged so that the insides thereof face each other, and a bridging member 4 having a concave portion 3... Connection members 5, 5 are arranged to form a U-shaped frame 6, and the two leg members 1, 1 are parallel to each other in a vertical direction.
An inverted L-shaped guide portion 9 for roller guidance is provided, which has a guide portion 7 for the roller and which is connected to the lateral direction from the upper end and has a concave portion 8 for roller lateral suspension. Is a pair of pressing rollers 10 with shafts protruding at both ends,
10 are inserted into the guide portions 9..., And grips 12.
Can be moved up and down along the guide portions 9 by moving the grips 12 up and down, and can be installed in the horizontal recess 8.

Since the rollers 10, 10 squeeze the sealing material while sandwiching the bag, the gap between the rollers is set to be approximately equal to or less than the thickness of the bag, and when the rollers are moved with respect to the bag. So that the roller rotates and the sealing material can be efficiently squeezed out,
It is preferable to use a material that does not slip on the bag material.
As such a material, for example, a polypropylene resin, a silicone resin, a polyurethane resin, a polyvinyl chloride resin, or the like is effective. Can be used. In this case, the sealing material can be efficiently squeezed while pressing the bag by the elasticity of the resin in addition to the holding force of the two pressing rollers. At the upper part of the U-shaped frame 6, a bag holding portion 13 is provided. This holding part 13 is
Since it becomes the connecting member at the upper end and the holding means for the bag body, a structure that can be easily attached above the leg members 1 and 1 is desired. Possible bending pieces 14 are provided on both sides of the holding portion, and the leg members 1, 1
By being fitted to the upper end of the frame, the upper part of the frame has a connecting function. The holding portion 13 is provided with an opening 15 for attaching and detaching the bag, and a serrated projection 16 for engaging the bag is provided adjacent to the opening.
, A hook-shaped projection 17 for hooking, which can be inserted into a hooking hole provided in advance in a gripping seal portion of the bag body.
・ It is provided. The bar-shaped projections 17 are desirably installed to be inclined rearward in order to more securely engage the margin seal portion. The manner in which the seal portion is engaged is described in more detail with reference to FIG.

That is, as shown in FIG.
3 are inserted through the catching holes 20 provided in the gripping seal portion 19 of the bag body 18. Subsequently, the bag 18 is hung down as shown in (b),
The gripping seal portion 19 is hooked on the hooking serrated projection 16. By adopting such a hooking mode, the saw-tooth-shaped projections 16 bite into the margin seal portion 19 appropriately,
In combination with the locking force of the rod-shaped projections 17, the bag 18 has its own weight against the weight of the bag 18 and the hanging force of the roller 10 at the time of squeezing.
Can be securely latched and held.

FIG. 3 shows how the sealing material is squeezed out. Bag body 18 hung by holding portion 13
To the pressing rollers 10, 1 interposed by the guide portions 9.
The sealing material S is squeezed out into the mixing container 2 by moving the rollers 10 and 10 in the direction of the arrow while pressing by 0. In order to more reliably squeeze out the sealing material S, it is effective to set the intervals between the guide portions 9 so that the pressing rollers 10 can be in close contact with each other. Also, as shown in the example of the drawing, for the maintenance of the rollers 10 and 10, it is also conceivable to provide holes 8a for extracting the rollers. If this device is used, the pressing rollers 10 and 10 can be operated with both hands as shown in FIG.
In combination with the reliable holding of the bag body by the hook-shaped projections 17 and the saw-toothed projections 16, the squeezing operation can be performed more easily. In this method, the unused sealing material remaining in the bag after squeezing was 1% or less in weight ratio, and it was confirmed that there was no problem as a sealing material squeezing device.

In addition, since the sealing material S adheres to the surfaces of the pressing rollers 10 and 10 at the end point of the squeezing, complicated cleaning work may be necessary. An elimination structure is proposed as FIG. In the illustrated example, each pressing roller 10
10 are provided at the lower part thereof, and are fixed to the fixed shafts 21.
The curtains 20 and 20 are provided so as to cover the surface of. When setting the bag, the curtains 20, 20 are located at the positions indicated by solid lines, and the pressing rollers 10, 1
While covering the surface with the droop of 0, the pressing roller 10, up to the dotted line portion which is the end point of the squeezing work,
It follows the movement of ten. Then, after performing the squeezing operation several times, the curtains 20, 20 to which the sealing material S has adhered may be replaced with new ones. The material of the curtains 20, 20 is not particularly limited, such as synthetic resin, paper, cloth, etc., but the sealing material S after curing can be easily peeled off and is inexpensive in cost. A film, a polyethylene film and the like are particularly suitable, and it is particularly preferable to provide mesh-like irregularities on the surface to prevent slippage. Then, for example, the end may be machined into a cylindrical shape and the fixed shaft 21 may be inserted therethrough, or the fixed shaft 21 may be attached to the fixed shaft 21 by an easily detachable method such as being wound around and fixed with an adhesive tape or the like.

Even when such a squeezing device is used, the gap between the pressing rollers 10, 10 is partially excessive or insufficient in the width direction during the squeezing operation due to a variation in the thickness of the bag body, and the squeezing operation can be performed smoothly. Can not do,
Remaining squeezing may occur. In such a case,
The gripping force of the grips 12... Is increased with respect to the remaining squeezing. On the contrary, if the squeezing operation cannot be performed smoothly, the gripping forces of the grips 12. What should I do? Further, after the work is completed, the pressing rollers 10 and 10 may be moved to the remaining part of the squeezing, and the squeezing work may be performed again. As described above, in the present invention, the problem in the squeezing operation due to the variation in the thickness of the bag body can be corrected extremely easily by adjusting the gripping force of both hands holding the grips 12 while observing the squeezed state. It is.

[0015]

[Effect of the invention] The sealing material squeezing device of the invention is
While securely holding the bag body with the bar-shaped projections and the serrated projections, the grips at both ends of the pressing roller can be held with both hands.
Since the squeezing operation is performed while being simultaneously held, the holding of the bag body is ensured and the pressing roller can be operated with both hands, so that the squeezing operation with extremely high workability can be performed. Also, since the holding of the bag is ensured, even if the force applied to the bag at the time of squeezing increases due to the increase in the viscosity of the sealing material at a low temperature, the squeezing operation can be performed without the bag coming off. Since the bag can be opened using both hands, the opening operation is also facilitated. Further, even when a problem occurs due to an excessive or insufficient roller gap, the correction can be quickly performed only by adjusting the gripping force of the handle, so that waste due to the remaining aperture can be eliminated.
